The ACID ROOKIE 50 20” mudguard set is compatible with the CUBE Ella 200 and Numove 200 with a maximum tyre width of 1.4in. This child-specific design features the exact same clever finishing touches as the adult versions: glossy finish icon details, the ACID adapter system and the integrated lighting cable guide. The mudguards are compatible with our ACID rear light integration technology. The set also includes stays.
